Pressure measurement suitable for negative-pressure applications, enabling high- and low-limit alarms by comparing the measured pressure value with a setpoint. The output signal is a passive dry-contact relay (SPDT). Common applications include: 1. Vacuum pump start/stop control; 2. Vacuum level monitoring and interlock systems for pipelines or containers. The pressure switch directly outputs a switching signal, delivering functionality equivalent to that of a pressure transmitter combined with PLC/control instrumentation for switch-based control. With its simple design, it excels in local control scenarios within compact-sized systems. This product features the following key characteristics: <br/> ● Fully welded diaphragm, zero leakage <br/> ●Mechanical principle, no power supply required <br/> ● High-quality microswitch with minimal dead zone <br/> ● The process interface is versatile, and both flanges and threads can be customized. <br/>
Suitable for differential pressure measurement in both explosion-proof and non-explosion-proof areas, this device compares the measured pressure difference with a set value to trigger high- and low-limit alarms. The output signal is a passive dry-contact relay (SPDT). Common applications include: 1. Filter clogging prevention control; 2. Differential pressure balancing control between two vessels. The pressure switch directly outputs a dry-contact signal, enabling functionality equivalent to that of a pressure transmitter combined with PLC/control instrumentation for switch-based control. With its simple design, it excels in on-site control scenarios within compact systems. This product features the following key characteristics: <br/> ● Fully welded diaphragm, zero leakage <br/> ●Mechanical principle, no power required <br/> ● High-quality microswitch with minimal dead zone <br/> ● The process interface is versatile, and both flanges and threads can be customized. <br/>
Suitable for applications involving corrosive, viscous, easily crystallizing, or substances prone to solidification and containing suspended solids. The diaphragm is internally filled with inert silicone oil, while the special-material diaphragm directly contacts the process medium. The silicone oil transmits pressure to the sensor, enabling high- and low-limit alarms by comparing the measured pressure value against preset thresholds. The output signal is a passive dry-contact relay (SPDT). Common applications include: 1. Acidic tail-gas pressure monitoring and alarm systems; 2. Pressure control in reaction vessels, etc. The pressure switch directly outputs a dry-contact signal, delivering functionality equivalent to that of a pressure transmitter combined with PLC/control instrumentation for switch-based control. With its simple design, this product excels in on-site control scenarios within compact systems. Key features of this product include: <br/> ● Fully welded diaphragm, zero leakage <br/> ●Mechanical principle, no power supply required <br/> ● High-quality microswitch with minimal dead zone <br/> ● The process interface is versatile, and both flanges and threads can be customized. <br/>
